# On Gesture
|
|
|
|
Start an [event handler](/reference/event-handler) (part of the
|
|
program that will run when something happens) This handler works when
|
|
you do a **gesture** (like shaking the @boardname@).
|
|
|
|
```sig
|
|
input.onGesture(Gesture.Shake,() => {
|
|
})
|
|
```
|
|
|
|
## Parameters
|
|
|
|
* ``gesture`` means the way you hold or move the @boardname@. This can be `shake`, `logo up`, `logo down`, `screen up`, `screen down`, `tilt left`, `tilt right`, `free fall`, `3g`, or `6g`.
|
|
|
|
## Example: random number
|
|
|
|
This program shows a number from `2` to `9` when you shake the @boardname@.
|
|
|
|
```blocks
|
|
input.onGesture(Gesture.Shake,() => {
|
|
let x = Math.randomRange(2, 9)
|
|
basic.showNumber(x)
|
|
})
|
|
```
